does any one know if you have to get a different exhaust if i snorkle my quad? i read some were if you put the right exhaust on you let it idle under water as long as your snorkle is out of the water? what about back pressure?

 

You dont need to change the exhaust. They run the exhaust up high incase it dies in the water or it will cause a vacuum and suck water right in. As long as it stays running you dont have to run the exhaust up . There is way more exhaust pressure going out than the backpressure of the water.

 

do you know how good these thing work?
